Crushed Iron Ore is created by crushing Iron Ore in one of three different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The two lover crafting stations also have a byproduct of Crushed Sandstone. Crushed Iron Ore needs to be further refined to Iron Concentrate before it can be smelted into an Iron Bar.
